Curvature-undulation coupling as a basis for curvature sensing and generation in bilayer membranes. [PDF]
Proc Natl Acad Sci U S A, 2016 Significance Most intracellular trafficking and many intercellular communications are orchestrated by curvature-driven or curvature-associated cellular processes. Hence, understanding how proteins sculpt lipid bilayers is vital to our understanding of how cell membranes modulate cell signaling pathways and consequent cell fate.

Curvature Sensing by a Viral Scission Protein [PDF]
Biochemistry, 2016 Membrane scission is the final step in all budding processes wherein a membrane neck is sufficiently constricted so as to allow for fission and the release of the budded particle. For influenza viruses, membrane scission is mediated by an amphipathic helix (AH) domain in the viral M2 protein.

The long and short of membrane curvature sensing by septins. [PDF]
J Cell Biol, 2019 Septin proteins form hetero-oligomers that associate with membranes of specific curvatures, but the mechanism is unknown. In this issue, Cannon et al. (2019. J. Cell Biol. https://doi.org/10.1083/jcb.201807211) identify a single amphipathic helix that is necessary and sufficient for membrane curvature sensing by septins.

Tafazzin senses curvature [PDF]
Nature Chemical Biology, 2012 The phospholipid-lysophospholipid transacylase tafazzin is responsible for enrichment of the cardiolipin fraction of mitochondria with tetralinoleoyl-cardiolipin. The specificity for linoleoyl hydrocarbon chains is now explained by the specific action of tafazzin on negatively curved lipid monolayers.
